dc.description.abstractTwo groups of finite element models have been carried out over Tertiary paleostress fields deduced from fault-slip data in the eastern part of the Tajo Basin. The first group corresponds to cover paleostress modelling, and the second one to basement paleostress modelling. Three different paleostress fields have been made for each group. Obtained results from two regional stress fields models show that maximum horizontal stresses (SHMAX) are controlled by two factors: limits geometry and boundary co nd itio ns applied on these lim its. A local stress field ( "A lto m ira ") appears by means of an addition of the two major paleostress fields ("Iberico" and "Guadarrama"). Different paleostress fields due to reological contrasts between different basement blocks have been investigated. Results on this kind of models show that a decouple between the cover and the basement paleostress fields could have been possible, specially for the "Altomira" paleostress field. Finally, model results are discussed related to Altomira Range originen_US
